Accessport Installation
Mounting Options
A universal ‘sticky’ mount is included with the Accessport. For the best results, we recommend installing the mount vertically, and preparing the mounting surface with the included alcohol wipe.
NOTE: It’s important to note that not all surfaces provide a strong adhesive bond. NOTE: The Accessport cradle is compatible with “Dual T” style mounts.
Pre-Installation
The Accessport comes with the most up-to-date software and map files available at the time of
shipment. However, it is possible that updated software and/or map files have been made available
since the time of shipment. Therefore, the recommended procedure is to connect the Accessport to the
AP Manager software and download the latest firmware for the target vehicle. Please visit
www.cobbtuning.com/apmanager to download AP Manager and to find a link for the AP Manager
manual.
If you have issues transferring maps or updating the Accessport while using USB 3.0 ports, please try
using a USB 2.0 hub adapter.
NOTE: The Accessport is preloaded with a default set of maps for all cars that it supports. This
includes Stage1 (all octanes), Stage2 (all octanes), Anti-theft, Economy, and Valet. If you would
like to view all maps available you can visit the Maps section of our website.
IMPORTANT!
For installation purposes, it is important to ensure that the vehicle's battery has adequate
power for both the Accessport and the ECU. Because of this, it is recommended that all in-
car electronics and vehicle lights are turned off during the installation process to reduce
drain on the vehicle's battery. For improved safety during installation, a car battery charger
can be connected to the vehicle during the installation process.

Standard Tuning vs SD (Speed Density) Tuning
Standard Tuning uses MAF (Mass Air Flow) sensor for air flow calculations. COBB Tuning provides Off-The-Shelf (OTS) maps created using this calculation method.
SD (Speed Density) Tuning uses MAP (Manifold Absolute Pressure) sensor for air flow calculations. Users who prefer the vehicle to be tuned by this method must either have the vehicle professionally tuned or generate their own Accesstuner Race map. The Accessport will not be pre-loaded with Speed Density maps.
age | 10
Vehicle Identification
The Accessport will attempt to automatically determine the target vehicle for installation. Verify that the
identified vehicle is correct and press [OK] to confirm.
If an error occurs:
Please refer to the Troublshooting Section.
Map Selection
After the Accessport identifies the vehicle, it will present a list of maps. Maps that are not intended for
the identified vehicle are displayed in gray. The Accessport will reprogram the ECU with calibration data
from the map selected for installation; this will become the base data for the ECU. To ensure the best
performance, select the map that most closely matches the modification level of the vehicle.
If you are unsure about which map applies to your modification level, please visit the Maps section of
our website. You can find map notes for each of our maps by clicking on your vehicle and choosing
your intake type. The map notes will list the modification requirements for each of our maps.
Select a map and press [OK] to proceed with the installation. If you wish to see a longer description for
the highlighted map, press and hold the [OK] button on the desired map. After reading the description,
you can press [CANCEL] to go back to the map list or press [OK] to select that map and proceed with
the installation.
What Is A Map?
The Accessport reprograms the tuning parameters inside the factory engine control unit (ECU) using
map files, which contain specially written instructions for the Accessport to follow during the
reprogramming process. A map file can contain information for any number of different modifications or
enhancements to a vehicle, ranging from a race map for a heavily modified vehicle, to an economy map
for a stock vehicle. Through the use of the Accessport and different map files, the ECU can be
reprogrammed to accommodate virtually any vehicle configuration.
Save Stock ECU Program Data
After confirming the map to be installed, the Accessport will download the current stock ECU program
data from the vehicle. The Accessport saves this data for use during the uninstall process to ensure
that the vehicle is completely returned to stock. The download process will take a few minutes to
complete.
age | 11
WARNING!
If a previous installation of an Accessport is detected, you will be given the option to
overwrite it with a new installation. Be aware that the previous installation will be
permanently lost and unrecoverable. This detection may occur prior to saving the stock ECU
program data, in which case the ECU program data will not be saved. In the case of a
previous install, a stock ECU program supplied on the Accessport will be used when you
uninstall.
Install Accessport Programming
With the stock ECU data saved, the Accessport will automatically proceed with installation to the
vehicle. At this point, the Accessport reprograms the vehicle's ECU with new program data and
calibration parameters from the installation map file. This process will take several minutes to
complete.
Transmission Control Module (TCM) Flashing
If you are using an AP3-NIS-006, after installing the new map on the ECU, the Accessport will proceed with TCM flashing.
Follow the instruction to save stock TCM program data; it takes approximately 7 minutes to complete the operation. Press OK to continue with saving the stock data, or press CANCEL to skip the process.
After the Accessport downloads and saves the stock TCM program data, it will proceed with installation of TCM data to the vehicle. Choose from a list of TCM map options. For more information about what TCM map to use, please refer to section “Transmission Control Modules”.
age | 12
WARNING!
Do not disturb the Accessport and the OBD-II connector while installation is taking place.
Failure to do so may result in incomplete ECU reprogramming which will render the vehicle
inoperable. If an error occurs during the reflash, the Accessport will enter Recovery Mode
and attempt to recover the reflash.
Installation Complete
Follow all on-screen prompts on the Accessport to complete the installation process. The Accessport is
now fully installed and ready for use and the vehicle's ECU and TCM, if applicable, are now
programmed with new calibration data. The Accessport does not need to be plugged into the vehicle
for the calibration to be in effect. You can disconnect the Accessport at this time or leave it plugged in
to use any of the many features outlined below.
Please note that the Accessport is designed to work with only one vehicle at a time. Once the
Accessport is installed, it cannot be used with another vehicle until it is uninstalled from the
original vehicle.

You will be prompted to select a pre-loaded map. The same warning that applies to the installation process applies here as well (battery charge level, climate control turned off, turn accessories off, etc.)
TCM Adjustments (AP3-NIS-006 only)
There are two TCM tools that are included in the AP3-NIS-006 firmware.
Run Clutch Gear Learning: This will run the gear learning for the transmission. To use this option the car and transmission fluid must be warmed up to at least 81 degrees Celsius. When running the transmission gear learning the transmission must be in Park and the engine at idle. The Clutch Gear learning is performed during any regular maintenance and when the TCM or transmission is replaced.
o NOTE: Clutch gear learning can only be performed once in a drive cycle (the ignition switch ON->OFF->ON).
o NOTE: If clutch gear learning can't be performed, turn the car off and then back on, and then perform the clutch gear learning again.
Touch Point Adjust: This option in the Accessport will walk you through the process of setting the touch point values. The range for the touch points is -7 to +7. The factory sets the values all to 0. Touch point for each clutch is learned during the transmission learning process and trimmed/modified by the adjustments via the Accessport. The touch point is the point where the clutch starts to engage. This is used during accelerating from a stop. The capacitor alters the clamping force especially when it is fully engaged at full throttle.
Clutch Torque Capacities: 0: Initial setting +1 to +7: Clutch capacity up -1 to -7: Clutch capacity down If a shock or slip is large during gear shift and start-up, adjust the clutch capacity.
age | 25
* Higher horsepower GT-Rs can eliminate unwanted clutch slip with a +2 or +3 level of Clutch Capacity. Clutch Touch Points: 0: Initial setting +1 to +7: Move the clutch touch point closer -1 to -7: Move the clutch touch point farther In the event of strong creep power, poor start-up response, or excessive start-up shock, adjust the clutch touch point.
TPMS Learning
TPMS Learning is used to register new TPMS sensors, either from replacing existing sensors or new wheels. To use TPMS Learning you must have a TPMS registration tool that is compatible with the GTR.
For testing purposes we used: http://ktipst.com/
TPMS Learning Process:
1. Turn key position to “On”. 2. Connect the Accessport to your vehicle’s OBD port and select “Tune.” Then go to “TPMS
Learning.” 3. A prompt will appear with instructions on how to successfully program the vehicle’s TPM sensors.
Press “OK” to get the process started. 4. After completing step 2 exit the vehicle with the Tire Pressure Positioning Sensor Tool. Start with
the front driver side tire (front passenger for RHD cars). Point the rounded end of the device at the sensor through the tire (the sensor is located behind the tire on the valve stem). Then push the “Activation” button until the device beeps. The appropriate light should come on (315MHz for US and 434MHz for EU) notifying the sensor is set.
5. Verify the Accessport registered the tool’s activation of the sensor. This can be confirmed by checking if the Accessport says “OK!” next to the TPM sensor just programmed on its screen.
6. Repeat steps 3 and 4 for each tire working your way around the vehicle in a clockwise motion. It is important to note that the TPMS learning feature cannot be exited after starting. It will timeout after 3 minutes. If it does timeout during programming, the process will need to be restarted. The 3 minute timeout will reset after each sensor is registered to prevent any unwanted timeouts.
7. Once the final sensor is registered the process is complete. There may be variances in the amount of time pressure is actually displayed due to different TPM sensors. If readings are not instantly displayed on the GT-R gauges, some users may have to drive a few minutes before pressures are identified.

1. Ensure that the Accessport is running the most recent version of firmware. You can verify
this by connecting the Accessport to AP Manager.
2. If the Accessport is up to date and still cannot identify the vehicle, please contact
technical support. It is possible that you have an ECU type that we have never
encountered before (e.g. brand new model year, new world market ECU, etc.). Technical
support will instruct you on what to do next.
